VVAPPARATUS FOR HEATING AND AGITATING AIR.

SPECIFICATION forming part of Letters Patent N0. 622,863, dated April 11, 1899.

I Application led February 17, 1898. Serial No. 670,615. (No model.)

To all whom it may concern:

Be it known that I, EDWIN F. PORTER, of Boston, in the county of Suffolk and State of Massachusettsmave invented certain new and useful Improvements in Apparatus for Heating and Agitating Air, of which the following is a speciication.

My invention relates to improvements in apparatus for heating and agitating air; and its object is to thoroughly heat and diffuse a body of air throughout an apartment.

In carrying out my invention I use a fan with a gas or oil burner placed in front or behind the fan and in the region of calm at the vortex of the fan. By placing the burner in this location with relation to the fan the iiame is not appreciably disturbed by the violent action of the air as it is moved by the fan, as would be the case if it were placed elsewhere in relation to the fan. The heat as it rises from the burner is taken up bythe flow of air from the revolving fan and is diffused throughout the apartment, and by this construction a large body of air is more rapidly heated and thoroughly diffused throughout the apartment than is possible with the present stationary gas-radiator or gas-log, which imparts its heat to the air coming in contact therewith by the ordinary slow circulation, allowing it to ascend to the ceiling and remain stored, thereby heating the upper part of the room only.

My invention consists of certain novel features hereinafter described, and particularly pointed out in the claims. l

In the accompanying drawings,which illustrate a construction embodying my invention, Figure l is a perspective view of my improved gas or oil heater. Fig. 2 is a longitudinal section through the fan and burner and showing the means for supplying the burner with gas or oil.

Like letters of reference refer to like parts throughout both views.

On a suitable base A there is supported an electric motor B, which is operated by the circuit C. To the shaft D of said motor there Vis fixed at its outerend a fan E of ordinary construction. a suitable guard F, secured to the motor B by screws F. the guard F, which is made of tubing to conduct the gas from the supply tothe burner I-I at the Vvortex or center of the fan, and located in the supply-tube G is a gas and air mixer G'. The gas,with the air, passes through the tube F2, which forms one of the supports of the guard, into the tube Fwhichentirely surrounds the fan and from which one or more tubes F4, whichform a part of the guard F, lead the gas to the burner H. Located in 4 front of the burner I-I is a disk of wire-gauze or asbestos I, held in place on a suitable ring J secured to the guard to act as a screen to the flame for purposes of safety. lVhere gasoleneor oil is used, the same passes from the source of supply through the guard to the burner in a similar manner to that shown for gas.

In operation when the fan is revolving the air is thrown from the blades, producing a decided current of air excepting at the center near the hub, where there is a region of calm, which offers an opportunity to locate the burner Where the flame will be practically undisturbed by the revolution of the fan. The hot air from this burner rises and mingles with the flow of air from the fan and is blown about the room to be heated instead of rising bodying the same, what I claim as new, and

desire to secure by Letters Patent of the United States, is-

1. In an air heating and agitating apparatus, a source of heat'for heating the air, a fan .Located around the fan E is Gas is fed by the tube G to -v for diffusing the air heated by said source of heat, a support for holding said source of heat at the center of the fan in the vortex of motion, and a motor actuated independently of the draft of said source 0f heat for operating said fan.

2. In an air heating and agitating apparatus, gas 0r oil burners for heating the air, a

fan for diffusing the air heated by said gas 0r oil burners, a support for holding said gas or oil burners at the Center of the fan in the Vortex of motion, and a motor actuated independently of the draft of said gas or oil burners for operating said fan.

3. In an air heating and agitating apparatus, a fan for diffusing the heated air, a guard for said fan, gas or oil burners :for heating the air located on said guard at the center of the fan in the Vortex of motion, and a motor for operating said fan.

4:. In an air heating and agitating apparatus, a fan for diffusing the heated air, a guard for said fan, gas or oil burners for heating the air, one or more tubes forming part of said guard for supplying gas or oil to saidburners, and a motor for operating said fan.

5. In an air heating and agitating apparatus, a fan for diffusing the heated air a guard on said fan, gas 0r oil-burners for heating the air located at the center of said fan in the vortex of motion, one or more tubes forming part of said guard for supplying gas or oil t0 said burners, and a motor for operating said fan.

In testimony whereof I have signed my name to this specification, in the presence of two'subseribing Witnesses, this 11th day of February, A. D. 1898.
